Olecranon Bursitis Clinical Presentation

History
Patients with olecranon bursitis usually notice focal swelling at the posterior elbow.
Pain at the affected site is usually reported; however, the swelling is sometimes painless.
Pain is often exacerbated by pressure (eg, leaning on the elbow, rubbing against a table when writing with the ipsilateral hand).
Chronic recurrent swelling is usually not tender.
Frequent bumping of the swollen elbow occurs because it protrudes further than it normally would.
A history of isolated trauma (eg, contusion) or repetitive microtrauma may be present.
The onset of bursal inflammation may be sudden if it is secondary to infection or acute trauma.
The onset of bursal inflammation may be gradual if it is secondary to chronic irritation.
Physical
The most classic finding of bursal inflammation is posterior elbow swelling, which is clearly demarcated by its appearance as a goose egg over the olecranon process (see the image below).

The affected area may be warm and red, particularly in cases in which infection is present.
Skin inspection may reveal abrasion or contusion if there was recent trauma.
The patient's vital signs may reveal fever, but fever generally occurs only with advanced infection.
The affected elbow's range of motion (ROM) is usually normal, but occasionally the end-range of elbow flexion may be slightly limited due to pain.
Patients with systemic inflammatory processes (eg, rheumatoid arthritis) or crystal-deposition disease (eg, gout, pseudogout) may reveal evidence of focal inflammation at other sites. See the image below.

Olecranon fracture. Causes
Bursal inflammation may be caused by a variety of mechanisms. Due to the superficial location of the olecranon bursa, it is susceptible to inflammation caused by acute or repetitive trauma, and less commonly, infection.
Acute trauma (eg, falling onto a hard floor or an artificial-turf playing field and then landing on the olecranon process)
Minor cumulative trauma (eg, repetitively rubbing the olecranon region against a desktop during writing)
Infection caused by abrasion or laceration at the affected site or by seeding from hematogenous spread via bacteremia
Inflammation as part of systemic inflammatory process (eg, rheumatoid arthritis) or crystal-deposition disease (eg, gout, pseudogout)
